ABB three-phase inverter designed for commercial usage

ABB three-phase inverter is highly unique in its ability to control the performance of the solar PV panels, especially during periods of variable weather conditions.

Two independent MPPTs and efficiency ratings up to 97.8%

This transformerless device has two independent MPPTs and efficiency ratings of up to 97.8%. The wide input voltage range makes the inverter suitable to low power installations with reduced string size. It is available with an optional fully-integrated DC switch, fuse and remote controlled DC disconnect function. The unit is free of electrolytic capacitors, leading to a longer product lifetime.

The high speed and precise Maximum Power Point Tracking (MPPT) algorithm provides real-time power tracking and improved energy harvesting.

 Flat efficiency curves ensure high efficiency at all output levels ensuring consistent and stable performance across the entire input voltage and output power range.

The wide input voltage range makes the inverter suitable for low power installations with reduced string size.


  • True three-phase bridge topology for DC/AC output converter
  • Transformerless topology
  • Each inverter is set on specific grid codes which can be selected in the field
  • Wide input range
  • Dual input section with independent MPPT allows optimal energy harvesting from two sub-arrays oriented in different directions
  • Integrated DC disconnect switch in compliance with international standards (-S and -FS versions)
  • Natural convection cooling for maximum reliability
  • Outdoor enclosure for unrestricted use under any environmental conditions
  • RS-485 communication interface (for connection to laptop or datalogger)
